The wall of the storage shed is a composite wall made of two layers of material, separated by a layer of air.

A composite wall is a type of wall made from two or more layers of material bonded together to form a single, solid surface. It is often used as an exterior wall in commercial and industrial buildings, as well as in homes. The primary benefit of a composite wall is its strength and durability. It is also much more energy efficient than a single-layer wall, as the multiple layers provide extra insulation. Composite walls can also be made with a variety of materials, such as concrete, steel, insulated metal panels, and fiberglass.

The air acts as an insulator, slowing down the flow of thermal energy through the wall and keeping the shed cooler on hot days. The thickness of the two layers and the air gap between them provide additional protection against heat loss. The plywood is 1 inch thick, and the asbestos-cement board is 5 mm thick (roughly 0.2 inches).

Explanation:

For the first question, the normal strain developed in each wire is given by the following equation:

Strain = (Displacement/Original Length) x 100

Therefore, the strain in each wire is:

Strain = (2mm/2r0) x 100 = 100 mm/r0

For the second question, the average developed in the rubber band is given by the following equation:

Strain = (Change in Length/Original Length) x 100

Therefore, the average normal strain in the rubber band is:

Strain = (Change in Length/2r0) x 100

Where Change in Length is the difference between the length of the rubber band after it is forced into the frustum of the cone and the original length of the rubber band.

Pw is defined as (eD2)/2(k+1), where e is the explosive density, D is the detonation velocity of the explosives, k is the isentropic exponent, and in most cases, k = 3. dc and db are the charge diameter and borehole diameter, respectively.

Overpressure, often known as a blast wave, is the rapid appearance of a pressure wave following an explosion. The energy released in the first explosion, which determines how large the pressure wave will be, is what generates it.

When 1 kilogram of TNT is detonated at an overpressure of 230 kPa (33.4 psi), the blast wind is measured to be over 240 km/h close to the place of origin. It is possible to foresee how an injury may occur.

The National (American) Standard Pipe Taper (NPT) thread, which offers a 1 in 16 (34 inch) taper per foot, must be used to thread the conduit. Where linked to explosion-proof enclosures, it must be constructed wrench-tight and have all five threads fully engaged. Due to the factory-provided NPT entries, some listed explosionproof enclosures may only need 412 threads fully engaged; these are acknowledged as an exception to the rule.One of the most crucial installation requirements for conduit placed as a wiring technique for hazardous (classified) areas is that it must be wrenchtight.

The responsivity of the device can be calculated by dividing the number of electrons generated per second by the number of photons incident per second.

Responsivity = 550 electrons per second / 800 photons per second = 550/800 = 11/16

So, the responsivity of the device is 11/16

The energy of a photon is equal to Planck's constant times the frequency of the photon. The Planck constant, often known as Planck's constant, is a crucial physical constant in quantum physics. The mass-energy equivalency establishes the link between mass and frequency, while the constant establishes the relationship between a photon's energy and frequency.

The fundamental universal constant known as Planck's constant, or h, establishes the quantum nature of energy and links the energy of a photon to its frequency.The constant value in the International System of Units (SI) is 6.626070151034 joule-hertz1 (or joule-seconds). The dimension of Planck's constant is obtained by dividing energy by time, or action.

Therefore, The responsivity of the device can be calculated by dividing the number of electrons generated per second by the number of photons incident per second.

Responsivity = 550 electrons per second / 800 photons per second = 550/800 = 11/16

True. Mufflers are used in many fully hermetic compressors to muffle compressor pulsation noise.

Mufflers work by creating a barrier between the compressor and the environment, which helps to reduce the noise created by the compressor's pulsation.

Mufflers are typically made of metal or other materials that are designed to absorb sound energy. The muffler works by using a combination of sound-absorbing materials, such as foam and fibreglass, as well as a series of chambers and baffles to dampen the sound energy and reduce the noise produced by the compressor.

When looking for a value in an array with 2,000 elements, a binary search function can only compare 11 elements at a time.

An effective method for selecting an item from a sorted list of items is binary search. It works by repeatedly dividing the part of the list that could contain the item in half until you can only find one place to put it. Find an item in an array is one of the most common uses of binary search. For instance, the Tycho-2 star catalog details the 2,539,913 brightest stars in our galaxy. Let's say you want to look for a specific star by its name in the catalog. In the worst case, the computer would have to look at all 2,539,913 stars to locate the star you were looking for if the program examined each star in the catalog in ascending order, using an algorithm known as linear search. Even in the worst scenario, binary search would not need to examine more than 22 stars if the catalog were sorted alphabetically by star names.

What is a turbine?

A turbine is a machine that converts rotational energy from a fluid captured by a rotor system into usable work or energy.

Turbines generate electricity through either mechanical gearing or electromagnetic induction. Turbines can be steam turbines, wind turbines, gas turbines, or water turbines. Mechanical applications of turbine power date back to ancient Greece. The first wind wheels used gearing and shafts to power machinery. Windmills and water wheels are also types of turbines that can drive a millstone to grind grain, among other things.

Thermal steam turbines powered by oil or coal, or nuclear power, are still among the most common methods of producing electricity.

Energy consumed by each house/year =  10,900 kWh

Energy generated by the turbine/week =   10.5 MW = 10,500 kWh

One year has 52 weeks.

Energy generated by the turbine/year = 10,500 kWh * 52 = 546000 kWh
